SWY Universal Sand Strength Machine SWY Universal Sand Strength Tester

Product Description

 

1. Technical requirements:
Used to measure the compression resistance of mold (core) sand at room temperature. Shear. Flexural. Tensile strength. Using manual hydraulic loading, the pressure gauge directly displays the test results, and can maintain a large destructive value.
1.1 piston to produce super thrust: 2400N;
1.2 Measuring range: 0-2400N; Measuring range of sand test: 1.3 Measuring accuracy: ±2.5%
SWY hydraulic strength machine digital display instrument is a universal hydraulic strength machine supporting the use of intelligent digital instrument. It is easy to carry and operate.
SWY hydraulic strength machine digital display is equipped with advanced high-speed SoC embedded computer, CNC programmable gain amplifier, high-precision 24-bit ∑- analog-to-digital converter and high-brightness LED display and other components, which can automatically complete the whole process of testing, data processing and display. It is widely used to test the strength of casting sand.

2.SWY hydraulic strength machine digital display instrument 
2.1 Instrument Panel
The instrument panel is composed of an intensity display area, an indicator light and three keys, as shown in the figure.

2.2 Indicators
1.  Tensile strength indicator light.
2. Compressive strength indicator light.
3. Bending strength indicator light.
4. Shear strength indicator light.
5.Standard sample indicator light. The indicator light is on, the test sample is the standard sample; When the indicator is off, the test sample is non-standard. Non-standard sample sizes are shown in Table 2.
Nonstandard sample size specification

	Tensile specimen	Compressive specimen	Flexural specimen	Shear specimen
Sample size	22.36x11.18	Φ30x50	22.36x11.18 x60	Φ30x50
Sample cross-sectional area	250mm^2	706.86mm^2	250 mm^2	1500mm^2

2.3 Keys and Their Functions The touch button consists of three keys. Mainly used for function setting and reset operations.
1. SET
 a. Short press SET . Select pull, press, bend, shear test mode, the corresponding indicator light on.
b. Touch &HoldSET. Select standard and non-standard samples. Press this key until the standard indicator light is on or off.
2.  RESET
Reset key. Used for instrument clear zeroing operation.
3. KEEP
KEEP key (reserved by manufacturer). The current function is the same as the Reset key.
3 Procedure
3.1 Startup and System Initialization
Connect the power adapter to the instrument and connect it to the 220V AC power supply. Initialize the instrument and self-test the display and sensor respectively. Strength display area displays "0000" - "9999". After the self-test is completed, the instrument will automatically enter the test state. Under normal circumstances, the strength display area will display "0"; The error number is shown in Table 3.
3.2 Changing the Test Mode
The corresponding test mode should be selected according to the sample. In the test state, you can SET change the test mode by pressing the button, and the instrument will automatically record and save the current test mode.
3.3 Measurement
When the instrument is in the measuring state, place the sample, turn the handle clockwise to load the sample until the sample is damaged, and the instrument flashes the test result. Turn the handle counterclockwise to reset the cylinder and record relevant experimental data. Press the button RESET, the instrument automatically clear, ready for the next test.
After the test, cut off the power.
